Is set to be the same as the width dimension of the first sheet 102. That is, the second sheet 108 is made of the same material as the first sheet 102. The second sheet 108 is arranged such that its surface 108A overlaps the surface 102A of the first sheet 102, and one end of the second sheet 108 and the other end of the first sheet 102 are “intermediate sewing”. The third sewing portion 110 as a “section” is sewn along the sheet width direction. Thereby, the 1st sheet | seat 102 and the 2nd sheet | seat 108 are integrated.

  On the other hand, a J hook 112 is sewn to the other end portion of the second sheet 108, and the J hook 112 has a substantially J shape opened to the rear side of the seat in a side view and extends in the seat width direction. Has been extended. The other end of the second sheet 108 is disposed on the back side of the ottoman body 80, and the J hook 112 is locked to the wire 78 of the support frame 76 described above. The J hook 112 may be configured to be locked to the finisher 82 (the ottoman body 80).

  Here, as shown in FIG. 4, when the ottoman main body 80 is rotated to the leg placement position, the protective sheet is such that the first sheet 102 and the second sheet 108 are substantially straight in a side view. The length of the unit 100 in the extending direction is set. That is, in this state, the tension in the extending direction of the protective sheet unit 100 acts on the first sheet 102 and the second sheet 108 by the wire 78 and the cushion trim 20 of the ottoman device 40, and the surface of the first sheet 102. The first sheet 102 and the second sheet 108 are developed such that the surface 108A of the 102A and the second sheet 108 constitute the upper surface of the protective sheet 100. At this time, the link mechanism 42 is disposed on the lower side of the protective sheet unit 100.

  On the other hand, as shown in FIG. 3, when the ottoman body 80 is rotated (stored) to the storage position, the first sheet 102 is arranged to extend from the portion of the second sewing portion 106 to the rear side of the sheet. At the same time, the protective sheet unit 100 is folded from the site of the third sewing portion 110 as a starting point.

  Next, the operation and effect of the present embodiment will be described.

  When the ottoman device 40 is used in a state where the ottoman main body 80 is disposed at the storage position, a current is supplied to the motor of the ottoman device 40 by the operation of the occupant. Thereby, the feed screw 74 is rotated and the link mechanism 42 of the ottoman device 40 is operated, whereby the ottoman body 80 is rotated to the leg placement position (see FIG. 4).

  When the ottoman main body 80 is rotated to the leg placement position, the ottoman main body 80 is disposed to be separated from the seat front side of the seat cushion 12, and the surface 102A of the first seat 102 and the surface 108A of the second seat 108 are disposed. The protective sheet unit 100 is deployed on the front side of the seat cushion 12 so that the upper side of the seat faces upward. At this time, the tension in the extending direction of the protective sheet unit 100 acts on the first sheet 102 and the second sheet 108 by the wire 78 and the cushion trim 20 of the ottoman device 40, and the first sheet in a side view. 102 and the second sheet 108 are linearly arranged. In addition, since the link mechanism 42 is disposed below the first seat 102 and the second seat 108, the protective sheet unit 100 prevents the link mechanism 42 from being exposed from the upper side of the seat, resulting in harm to the occupant. The feeling is suppressed.

  On the other hand, when rotating the ottoman body 80 from this state to the retracted position, a current is supplied to the motor of the ottoman device 40 by the operation of the occupant. Thereby, the feed screw 74 is rotated and the link mechanism 42 of the ottoman device 40 is operated, whereby the ottoman main body 80 is rotated toward the storage position.

  At this time, since the ottoman body 80 is rotated so as to be tilted downward while moving to the rear side of the seat, the tension on the protective sheet unit 100 by the ottoman body 80 and the cushion trim 20 does not act. . For this reason, the protective sheet unit 100 starts to bend in the direction in which the surface 102A of the first sheet 102 and the surface 108A of the second sheet 108 overlap each other with the site of the third sewing portion 110 as a starting point. That is, with the rotation of the ottoman body 80 to the retracted position, the protective sheet unit 100 is displaced so as to be gradually folded from the back side of the ottoman body 80 starting from the portion of the third sewing portion 110.
